In recent years, probiotic bacteria have increasingly been incorporated into various foods as dietary adjuncts. The viability of the probiotic bacteria Lactobacillus acidophilus NRRL B 4495 and Bifido- bacterium bifidum NRRL B41410 in salted (1% w/w) and unsalted lor whey cheese during storage (21 days) at a refrigerated temperature (4°C) was evaluated.
As well as the survival of the probiotic bacteria, total mesophilic bacteria, total lactic acid bacteria, Pseudomonas spp., yeast-mould counts and sensory characteristics were examined in the lor samples.
The Bf. bifidum remained in large numbers, at 7.30 and 7.11 log cfu/g, and Lb. acidophilus also survived well, with counts of 7.60 and 7.47 log cfu/g, for unsalted and salted cheeses respectively. Salted lor cheeses with added Lb. acidophilus have the highest sensory scores in the groups.
“Lor” whey cheese showed good probiotic properties.
近年来,益生菌越来越多地被作为膳食辅助成分添加到各种食品中。对嗜酸乳杆菌NRRL B 4495和两歧双歧杆菌NRRL B41410在冷藏温度(4℃)下储存21天的加盐(1%w/w)和未加盐洛氏乳清奶酪中的存活力进行了评估。
除了检测益生菌的存活情况外,还对洛氏样品中的嗜温菌总数、乳酸菌总数、假单胞菌属、酵母菌和霉菌数量以及感官特性进行了检测。
对于未加盐和加盐奶酪,两歧双歧杆菌数量众多,分别为7.30和7.11 log cfu/g,嗜酸乳杆菌的存活率也很高,数量分别为7.60和7.47 log cfu/g。添加嗜酸乳杆菌的加盐洛氏奶酪在各组中感官评分最高。
“洛氏”乳清奶酪具有良好的益生菌特性。
